A boy walks at a speed of 4 mph. How much time does he take to walk a distance of 20 miles?
20/4 = 5 hours.
300
What is the change in position measured by distance and time?
Motion
400
What law states that F=MA?
Newton's Second Law of Motion

If there is a straight line on a speed-time graph, is the object at rest or in constant speed?
Constant Speed
400
If a balanced force is acting upon an object, will the object move?
No
400
What is the difference between speed and velocity?
Velocity is speed in a certain direction, while speed doesn't involve direction.
400
What is an object's resistance to change in its motion?
Inertia
500
What does Newton's First Law state and what force is associated with it?
An object at rest will stay at rest until a force acts upon it, and an object in motion will stay in motion until a force acts upon it. Inertia.
